That is such a broad question.
What are you doing in your business?
The major requirement for any business however is that you do not lose access to your documents or have them damaged.
The answer to that question is without a shadow of a doubt: DO NOT USE APPLE FORMATS*.
Not only are they proprietary, but Apple has on multiple occassions trashed not just formats but the files that use them. WITHOUT NOTICE or APOLOGY.
Also all the new iCloud compatible file formats are bloated, fail to transfer via 3rd party servers and are in such a convoluted compressed package that to extract anything from them in an emergency is impossible.
Apple has virtually no sense, or even consideration, of continuity or awareness of their customers' needs.
Apple is extremely self centred and it is very difficult to get it to think of anyone else except as some abstract theoretical consumer who only exists in that fabled land outside Cupertino, where no-one actually goes, except on short vacations.
